Patent EP-0260763-A2 (EP)
Inventor: SELBY GEOFFREY RICHARD
IPC: H04W88/02
Filed: 1987-09-17
Abstract: A mobile radio transmission system comprises a plurality of base stations (BS) with corresponding service areas (SA) which together cover a geographical area through which mobile stations (M) can roam. Each base station is connected to a central station (CS) by means of a respective two-way communication link (CL). In order that it can be contacted without all the base stations having to put out a call, each mobile station registers in known manner with the base station in whose service area it is situated, and this is recorded by the control station. When it roams into a new service area this process is repeated. However, in order to preclude frequent re-registrations when the mobile station repeatedly crosses the boundary between two service areas, when it registers with a new base station and hence a new service area it retains its registration with at least one service area with which it is already registered, thereby creating its own customised enlarged registration area. Thus the transmission overhead created by the registration procedure is reduced.

Abstract: A digital automatic line equalizer for compensating distortion of a digital signal transmitted through a transmission line comprises a transversal filter (11) having a set of tap gains for producing an equalized signal as a filter output from the digital signal incoming thereto. A first multiplier (200) squares a current one of the filter output to produce a squared signal and other multipliers (201-20ℓ) multiplies the current and the previous ones of the filter output to produce product signals. A calculator (21) calculates from the squared signal and the product signals a mean value of sum of the squared signal and weighed product signals for a predetermined time duration. A controller (15) determines a set of values from the mean value to make the set of tap gains equal to the set of values thereby to maintain the mean value to a predetermined value as a reference value so that the transversal filter (11) produces the equalized signal. The calculator (21) may comprise a plurality of weighing circuits (22) for producing the weighed product signals, an adder (25) for producing the sum, and an averager (26) for producing the mean value. A controller (15) may comprise a comparator (27) for comparing the mean value and the reference value to produce an error signal, a memory (30) for storing a   plurality of sets of values for the set of tap gains, and a selection controller (29) for selecting one of the plurality of set of values in response to the error signal.

Abstract: A voltage controlled oscillator comprises a phase locked loop section (1) and a voltage controlled oscil­lator section (2). The phase locked loop section (1) is coupled with an input signal (Fref) at a reference frequency and a reference potential (Vref), and performs a signal feedback control so as to obtain a constant delay time of a first variable delay circuit (3) con­tained in the phase locked loop section. The voltage controlled oscillator section (2) controls a delay time of a second variable delay circuit (10) in a ring oscillator by a control input voltage (Vcont) and an output voltage (Voff) of a low-pass filter (7) contained in the phase locked loop section, and produces a signal oscillating at a frequency as determined by the delay time. In the voltage controlled oscillator thus ar­ranged, the output frequency is determined by control­ling a delay time of the second variable delay circuit in the voltage controlled oscillator section. Since the delay time is accurately controlled by the phase locked loop section, the obtained output frequency is stable against the variance of the process parameters. Since the delay time is varied by the reference frequency of the input signal, the output frequency may be set at a desired frequency, and hence a frequency band of the oscillation frequencies may also be set appropriately.

Abstract: In a process for optimising the running properties of synthetic yarns during air texturing processes by wetting the yarns by spraying with process water as the yarns pass through a texturing nozzle, polyalkylene glycol compounds are added to the process water. The molecular weights of the polyalkylene glycol compounds range from 1,000 to 6,000 daltons, preferably from 2,000 to 4,000 daltons. The final concentration of the polyalkylene glycol compounds added is between 2 and 6 per cent by weight, preferably between 3 and 5 per cent by weight. Process water which has been treated in this way prevents the undesirable lodging of fibre deposits in the nozzle unit, extends nozzle life, increases processing speed and reduces process water consumption.

Abstract: A change-speed lever apparatus for use in a bicycle. The apparatus has a winding member (20) for winding up a change-speed control cable and a cable-­pulling lever (60) operable to pull the cable by causing the winding member to pivot only in a cable winding direction. The cable-pulling lever returns to its home position after completion of change-speed operation. The improved apparatus includes a position maintaining mechanism for stepwisely maintaining a position of the winding member and a release lever (70) operable to release the position maintaining mechanism. The release lever also returns to its home position after completion of release operation. At the respective home positions, the cable-pulling lever and the release lever are operable in substantially same directions to enable a cyclist to disregard the direction of lever operations. Further, the home positions of the levers are disposed at different yet adjacent locations relative to a direction normal to the lever operating directions. Hence, the lever operations, i.e. change-speed operations do not require much movement of the cyclist's thumb. Consequently, the apparatus provides speedy and accurate change speed operations.

Abstract: A multi-bus microcomputer system includes a cache subsystem and an arbitration supervisor. A CPU is provided with a PREEMPT signal source which generates a preempt signal in CPU cycles extending beyond a specified duration. The preempt signal is effective at any device having access to the bus to initiate an orderly termination of the bus usage. When that device signals its termination of bus usage, the arbitration supervisor changes the state of an ARB/GRANT conductor, which had been in the grant phase, to the arbitration phase. During the arbitration phase each of the devices (other than the CPU) cooperates in an arbitration mechanism for bus usage during the next grant phase. On the other hand, the CPU, having asserted preempt, responds to a signal indicating initiation of the arbitration phase by immediately accessing the system bus.
